Driving the creation and industrialization of a dedicated BESS business unit, defining the industrial, operational and organizational architecture required to build and scale energy storage capabilities. • Defined the industrial and operating model for BESS deployment, aligning engineering, manufacturing and execution with cost structure, scalability and business objectives • Structured the business unit from the ground up, establishing governance, cross-functional integration and decision frameworks • Led key industrialization decisions shaping CAPEX, production setup and supplier strategy, including pre-series manufacturing and transition to scalable production • Defined the industrial cost structure, CAPEX framework and deployment model supporting a multi-million revenue base, aligning product architecture, manufacturing and supplier strategy • Directed certification, validation and deployment readiness across low and high voltage product lines Resulting in: • HIMOINSA–YANMAR’s entry into energy storage through a structured and scalable industrial platform • A scalable industrial foundation linking system architecture with manufacturability, cost structure and deployment capability • Alignment of multidisciplinary teams and external ecosystem (suppliers, laboratories, partners), ensuring system validation and industrial readiness

Supported industrial clients and investors in energy transition, electrification and energy-market optimization, combining technical, commercial and operational perspectives to structure viable and scalable projects. • Delivered techno-economic analysis and deployment strategies for renewable energy, electrification and energy efficiency projects across industrial environments • Structured and executed on-site PV PPA schemes, covering technical definition, commercial structuring, contract negotiation and financing, enabling scalable multi-site industrial deployment (4 installations, 3.75 MWp, 20-year term) • Developed industrial energy master plans, including hybrid PV solutions (~15.75 MW / 4 MWh), supporting long-term electrification strategies • Managed energy procurement and contract optimization across 750+ electricity supply agreements, improving cost efficiency and contractual performance • Advised large-scale, multi-site industrial operations (e.g. fuel retail networks with 150+ locations), integrating grid connection, tariff optimization and energy efficiency across distributed assets

Oversaw large-scale industrial operations within a complex, multi-project railway manufacturing environment, managing multi-layer teams and production systems under demanding delivery constraints. • Managed an industrial organization of 250+ people across multiple levels, integrating production, engineering and support functions • Redesigned production systems and operational workflows to improve efficiency, stability and delivery performance in a multi-project environment • Coordinated concurrent industrial programs with high interdependencies, aligning production capacity, planning and execution • Strengthened operational governance, improving cross-functional coordination and increasing reliability of delivery This resulted in: • >25% reduction in lead time across complex production programs • Improved operational efficiency and system stability in a high-complexity industrial environment • Increased delivery reliability under multi-project conditions and demanding timelines

Senior operational leadership role in an industrial manufacturing environment, with responsibility for operations, engineering and production planning, driving execution discipline, team performance and process stability in a growing organization.

Early leadership role combining technical and operational responsibilities in an industrial automation environment, supporting product development, production engineering and organizational growth within international projects.

Early technical and engineering roles within industrial manufacturing, focused on product development, process improvement and operational execution, building a solid foundation in industrial engineering.
